System.IO.Directory exposes static methods for creating, moving, and enumerating through directories and subdirectories

This link shows how to add attachments to a MailMessage

You can send a MailMessage with the SmtpClient class

I have put the code in this message. Happy coding. I typically didn't do all the code for someone. But I thought this example will get you further then the previous links. You will need to reference the name spaces System.OI and System.Net.Mail
Make sure to mark this as the solution if it works out for you.

//If you want to control how many folder deep to scan in target

    const int HowDeepToScan = 4;

    public static void ProcessDir(string sourceDir, int recursionLvl)


        MailMessage MyMail = new MailMessage();

        MyMail.From = "";  

        MyMail.To = "";

        MyMail.Subject = "Your Subject";

        MyMail.Body = "This is the body of the message";

        SmtpMail.SmtpServer = "";


        if (recursionLvl <= HowDeepToScan)


            // Process the list of files found in the directory. 

            string[] fileEntries = Directory.GetFiles(sourceDir);

            foreach (string fileName in fileEntries)


                // do something with fileName


                //Attach File to MyMail Object

                MailAttachment attachment = new MailAttachment(Server.MapPath(fileName));



            // Recurse into subdirectories of this directory.

            string[] subdirEntries = Directory.GetDirectories(sourceDir);

            foreach (string subdir in subdirEntries)

                // Do not iterate through reparse points

                if ((File.GetAttributes(subdir) &

                     FileAttributes.ReparsePoint) !=


                    ProcessDir(subdir, recursionLvl + 1);
